Work by Lamont's John Armbruster and colleagues that have linked earthquakes to underground fluid injection cited.
A 2013 study led by Lamont's Lex van Geen found that arsenic had leached its way into a major drinking-water aquifer servicing Hanoi.
A price on carbon is needed before capture and storage of CO2 becomes a viable option, says Lamont's Peter Kelemen.
A floating pool scheduled to open in the East or Hudson Rivers in 2016 will use a filtration system that Lamont's Wade McGillis has helped to design.
MESSENGER has been getting closer to Mercury since March and is now closer to the planet than any spacecraft has been before. "Mercury has stubbornly held on to many of its secrets, but many will at last be revealed,” says Lamont director and MESSENGER principal investigator Sean Solomon.
Lamont's Deputy Director Arthur Lerner-Lam discusses the need for better communication of natural hazard risks.
“On some level, watching these milestones be passed is a lot like watching paint dry,” said Lamont's Jason Smerdon. “The upward march is neither surprising nor unexpected as a direct consequence of human activities; it is only alarming in the sense that it keeps happening unabated.”
A new study is helping astrobiologists understand how climate change may shape the future of life on Earth. Coverage of a study in Climate Dynamics by Lamont's Benjamin Cook, Jason Smerdon and Richard Seager.
With the Ganges–Brahmaputra delta sinking, the race is on to protect millions of people from future flooding. Work of Lamont's Michael Steckler cited.
Using tree rings, Lamont's Neil Pederson and colleagues have created a record of droughts dating back hundreds to thousands of years.
Lamont-Doherty seismologist Geoff Abers comments on the possibility that a pair of deadly earthquakes in Italy in 2012 were triggered by petroleum extraction at a local oil field.
Cites research by Lamont-Doherty microbiologists Joaquim Goes and Helga do Rosario Gomes.
Lamont climate scientist Maureen Raymo featured in a video interview.
“Plate tectonics was originally proposed as a kinematic theory — it was about displacements, movements and velocities,” said Lamont deputy director Arthur Lerner-Lam. “The great accomplishment was to link earthquakes to those movements.”
"For agriculture, the moisture balance in the soil is what really matters," said study co-author Jason Smerdon, a climate scientist with Columbia University's Lamont-Doherty Earth Observatory. "If rain increases slightly but temperatures also increase, drought is a potential consequence," he told The Hindu.
"Nowadays, we have to go out of our way to encounter sea ice, but this year was amazing. We ran into ice throughout the study area. It forced us to be creative when we couldn’t go where we wanted to," said Hugh Ducklow External Non-U.S. government site, lead principal investigator (PI) for the Palmer LTER and a professor of Earth and Environmental Sciences at Columbia University’s Lamont-Doherty Earth Observatory External Non-U.S. government site.
The model that best predicted earlier El Nino events, developed by scientists at Lamont-Doherty, did not see the destructive 1997-1998 event coming.
"We know from basic physics that warmer temperatures will help to dry things out," lead author Benjamin Cook said in a statement. "Even if precipitation changes in the future are uncertain, there are good reasons to be concerned about water resources."
The year is 20XX: Dallas is covered in 30 inches of snow, San Francisco is experiencing mild tornadoes, and Greenland has become a tropical paradise. At least, this is what inhabitants of possible futures are saying in the new alternate reality game, Future Coast.
Alexander van Geen, a geochemist at Columbia University in New York, US, has been focusing his efforts on testing wells that are already in use. In 2000, his team measured the levels of arsenic in 5000 wells in Bangladesh and, armed with the GPS location of each well, looked at the spatial variability. 'What was striking is that the distribution was very heterogeneous,' he says. 'We calculated that, over our area, 50% of the people had wells with water that they should not be drinking from. However, 90% of these same households lived within 100m of a safe well.'
